Hi there: During the past weeks (let's say since beginning of the year) we've been experiencing some issues with shifted components. We verify for position before Reflow oven and the components are Ok, but they observe shifted after reflow. it occurs

Just a comment, we have been using the OEE as metric in our plant, what I've seen is that can be misunderstood because a good OEE level does not mean a good machine utilization, let me try to explain this on my own words. I have a HMLV line, so when

Rob, Had that issue early on when we hooked up our Heller. For us, the problem turned out to be the serial communications port on the computer. I can't say we had the black screen, but, we had comm errors. I'd check the following: 1. Cable betwe
